Rodent poison spreader



Jame 30, 1936. G. REBHAHN RODENT POISON SPREADER Filed Jan. 23, 1935 ATTORNEY Patented June 30, 1936 UNITED STATES PATENT OFFICE 1 Claim.

The invention'relatesto-apoison dispensing device and more especially to a rodent poison spreader.

The primary object of the invention is the provision of a device of this character, wherein the poisonous food, as for example, oats, meal, corn or other feed treated with poisonous matter, can be conveniently and easily dispensed, particularly at the point of location of the hole of a rodent, as for example, gophers, for the killing and exterminating of such pests.

Another object of the invention is the provision of a device of this character, wherein the substance to be dispensed can be delivered in a convenient manner in determined quantities, and particularly if the user is riding a horse, so as to direct the poisonous food at the desired place, the said device being capable of convenient carriage in the hand of a person and operable with dis patch and ease, without waste of the substance in the dispensing of the same.

A further object of the invention is the provision of a device of this character, which is simple in construction, thoroughly reliable and eflicient for the purpose intended thereof, capable of use when walking or riding horseback, readily and easily operated, light in weight to render the same readily portable, yet strong, durable, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described in detail, illustrated in the accompanying drawing, Which discloses the preferred embodiment of the invention, and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is a side elevation of a device constructed in accordance with the invention, the same being partly in section.

Figure 2 is a fragmentary end elevation partly in section.

Figure 3 is a sectional view on the line 33 of Figure 1 looking in the direction of the arrows.

Figure 4 is a sectional view on the line 4-4 of Figure 2 looking in the direction of the arrows.

Similar reference characters indicate corresponding parts throughout the several view in the drawing.

Referring to the drawing in detail, the device comprises a cylindrical body Hl forming a container for food substance treated with poison, as for example, oats, meal, corn or other feed for animal consumption. This body I 0 is closed at opposite ends except that a hinged gate I l is provided at one of these ends so that upon the opening of the gate, substance can be introduced into the body for the filling thereof. The gate carries a hand releasable spring latch I2 which releasably fastens such gate in cldsed position. 5

At the upper portion of the body l0 there is provided a handle 13, it being substantially the length of the body and by reason of its location at the uppermost portion thereof the device can be readily carried without undue strain on the wrist of 10 the hand of the person carrying the same. At the diametrically opposite portion of the body With respect to the handle is a delivery funnel l4, it having a neck l5 serving as a nipple for the detachable coupling therewith of a tubular nozzle l5 Hi to which is adapted to be applied a flexible discharge hose piece ll which is of the required length for directing the substance discharged from the body and this hose piece is serviceable when the user of the device is riding horseback. 20 The hose piece delivers the substance as contained within the body I0 for the deposit of such poisonous substance at the localities required, particularly next to a Hole for rodents, as for example, gophers.

The neck l5 of the funnel I 4 is provided with the bayonet slots l8 for fastening lugs or pins I9 carried by the nozzle l6 and in this manner the said nozzle is separably attached to the neck 15 of the funnel l4 so that the device can be used at 30 close range and in this the necessity for the hose piece is avoided, it being understood, of course, that the hose piece I! can be of the required length to permit the directing of the substance to be dispensedto a particular point for deposit 35 thereof when at long range.

Formed in the body It! for communication of the funnel I4 is an opening 20 which confronts a measuring hopper 2| fixed to and depending from said body into the funnel Hi. This hopper 40 2| measures a determined quantity of substance when deposited therein for the discharge of the determined quantity from the body l0, while Working through the said hopper 2|, which is open at opposite ends, is an ejector including the 45 slide 22 having the opening 23 corresponding in size to the opening 20 and normally registering therewith. Depending from the slide 22 are the end closure extensions 24 for the hopper 2| so as to retain a determined quantity of substance admitted into the hopper and to deliver such quantity therefrom into the funnel M for the dispensing of this quantity through the nozzle for its deposit onto the ground, preferably at the hole of the rodent. On eating of this substance,

"21 being formed with the finger piece 30 in convenient reach with relation to the handle [3 so that the finger of the hand of an operatorgrasping the handle can readily and conveniently manipulate the trigger for the operation of said device in the dispensing of determined quantities of Substanceas hereinbefore stated.

The slide 22 is held in normal position under the tension of a coiled spring 3! acting thereon and mounted, at '32, within the body IB of the device. 'This spring normally holds the slide 22 in a position so that the extensions 24 will close the opposite open ends of the hopper 21 and the latter will receive the determined quantity of' substance from the body iii of the device. When the trigger 27 is operated, the slide 22 will be shifted against the resistance of the spring 3| and the extensions 24 depending therefrom will eject the measured quantity of substance Irom the hopper 2| into therfunnel l4 and thence by gravity this measuredquantity of substance will be delivered or dispensed through the nozzle and hose piece for deposit.

What is claimed is: a

A device of the character described comprising 7 a cylindrical reservoir, a'discharge funnel at one side of the reservoir, a hose length detachably joined with said funnel, a measuring hopper within the funnel and depending from the reser voir and having discharge openings at opposite ends for delivering material from the reservoir to said hopper in determined quantities, a slide 7 operating within the hopper for ejecting material therefrom into the funnel, and means at one end of thereservoir for actuating said slide, the said,

slide and hopper being disposed crosswise of the 20 funnel while the slide operates longitudinally'of said reservoir; 7 GEQRGE REBHAHN.
